This 10 mm triple square is supplied with a permanent ½®€® drive base with an extra long overall length of 160 mm. The 10 mm is used for some starter mounting bolts, flywheel bolts and other applications. Some late model cars use this 10 mm on inner CV bolts, where the driveshaft attaches to the transmission. NEW: These bits are NOW long enough for the early 1.8T engines** that need 10 mm 12 point spline bits. Top quality Metalnerd® brand made from S2 tool steel.

** Note: If your early 1.8t has 12 point head bolts, the new bolts you buy for reassembly may arrive with the newer 6 spline found on our MN3452. We have both in a kit (18TKIT) that will save you $3 and possibly a headache!
